    McIntosh cabinet DIY results

    Hey guys. Wanted to share my results from making my own cabinet from the dimensions that I got off AK somewhere. Was a good lesson in woodworking.

    Designing a custom crossover.

    I have been designing crossover specifically for the drivers I have. I have never done this before, but I know that the goal is to flatten the response fairly well.

    Putting new equipment in a 1964 Magnavox console. Had two 5 inch mids pointing forward and a 12 woofer pointing out the side. That configuration for left and right side. They were not enclosed from behind, just in the cabinet itself. Thinking to build boxes around them for better sound...

    Marantz 2265, 2275, 2250B... P800 Power Supply/Protection PCB Replica

    I decided to recreate this PCB. Most probably they use this one in other Marantz models, that I'm not aware of... In the first place, I made a clean copy of the schematic (with the vintage look preserved, of course ;)): Then, when I was working with the PCB, decided to add an option for...

    Eliminating Empire 598 motor air noise

    Hi, we all know Papst motors are great, but do produce audible hiss. I was lucky to buy a NOS 698 motor which has no vibration - still its rotor moving air can be audible from 2-3 meters away in a quiet room. Standard resonant Empire wood plinth enclosure, open from below, actually amplifies...
